Non-Markovian effect on quantum Otto engine: Role of system-reservoir interaction
Physical Review Research, 2021 We study a limit cycle of a quantum Otto engine whose every cycle consists of two finite-time quantum isochoric (heating or cooling) processes and two quantum adiabatic work-extracting processes. Considering a two-level system as a working substance that

, 2022 Optical energy flow inside a dielectric microsphere exposed to an optical wave is usually codirected with its wave vector. At the same time, if the optical field in a microparticle is in resonance with a high-quality spatial eigenmode, referred to as the whispering-gallery mode (WGM), at least two regions of reverse energy flow emerge in the ...

Advanced Functional Materials, EarlyView.Resonant standing waves generate large‐area lattices of liquid‐crystal topological defects that are permanently encoded into polymer coatings by photopolymerization. The preserved director architecture produces thermally reconfigurable surface topographies while maintaining programmable optical functionality, demonstrating a scalable strategy for ...

Irreversible work and Maxwell demon in terms of quantum thermodynamic force
Scientific Reports, 2021 The second law of classical equilibrium thermodynamics, based on the positivity of entropy production, asserts that any process occurs only in a direction that some information may be lost (flow out of the system) due to the irreversibility inside the ...

Advanced Materials, EarlyView.This review examines passive, active, and hybrid liquid manipulation strategies, highlighting hybrid approaches as an emerging route to reconcile energy efficiency with adaptive control. By actively reconstructing passive surfaces to store programmable interfacial energy, hybrid systems enable flexible yet low‐power liquid transport, with perspectives ...

Generation of on-axis energy backflow via superoscillation focusing
Optics ExpressOn-axis energy backflow has recently been discovered in the focal fields of various light beams with phase or polarization singularities. However, although an azimuthally polarized beam superimposed with the first-order vortex phase satisfies the general conditions for achieving on-axis energy backflow, it is found to be difficult to induce this ...

Ion energy diagnostics in the plume of an SPT-100 from thrust axis to backflow region [PDF]
34th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 1998 Of primary concern with the integration of Hall thrusters on conventional satellite designs is the possible damaging effect of high-energy exhaust ions impinging upon spacecraft surfaces. This paper reports on measurements of plasma ion energy distributions within the plume of an SPT-100 Hall thruster using a custom-designed molecular beam mass ...
